Img src not loaded in Outlook email - html

I send the same email to gmail (the image is loaded correctly) and outlook (Failed to load the given URL).
In gmail i have this html code:
http://xxx/~mgxzbmdx/joomla/images/stories/virtuemart/vendor/logo.png
In Outlook this one:
https://dub113.mail.live.com/Handlers/ImageProxy.mvc?bicild=&canary=nUc%2fUMnrf0l9V5rzT3XB4Cb5axSzPUBWqwI5uP2ZjrU%3d0&url=http%3a%2f%2fx.x.x.x%2f%7emgxzbmdx%2fjoomla%2fimages%2fstories%2fvirtuemart%2fvendor%2flogo.png
Any idea about the reason?

The problem is the file type.
HTML emails should only use .gif or .jpg.
Try with a new picture format. I suppose you use a .png file because it has transparency? It saddens me that I have to tell you this, but you'll be better off faking transparency with split images in nested tables. That's the only way for a html-email not to break.

I think the issue lies with your method/software. Looks like your / are getting converted to %2f which gmail seems to be smart enough to interpret, but Outlook is not. See if there is something in Virtuemart or Joomla that you can turn off link encoding or something like that.

How many CSS attributes are stripped by Gmail?

I'm trying to send email by using Symfony and I found that I can't use position and background: url() because Gmail stripped them. So I want to know how many CSS attributes which Gmail stripped?
Gmail basically removes <head> tag and all "linking", like you mentioned background URL. This is vunerability because you can pass any data by encoding image (base64 encoding).
I belive Google never published details on this, but we can only presume.
I would suggest you bullet-proof test your mail here

Alternative to base64 Encoded Image sources (E-Mail Signatures)

I am trying to generate email signatures for my entire company so I am using a script to fill in an HTML template with each individual's information and generating an HTML file that I would like to use for the signature. The generation of the HTML works fine and I can load the HTML into chrome and it displays 100% correctly.
I would prefer to not have to host these images somewhere at the moment and would like them to be embedded in the e-mail. We can achieve this by using outlook on each individuals machine to create the signature by hand, but again we want to avoid that. Ideally, we will generate these templates and then automatically put these files on each employee's computer so all we have to do is select the signature from outlook.
The problem we are having is that when we do this, the image does not load. It seems that outlook won't allow base64 encoded images? I've tried to work around this by trying to attach the image to the email and then referencing it, but this doesn't seem to work either. I used this template. I got the boundary from a test email I sent myself, but I don't even know if this is a good way to go about this either.
In short, is there a way to create an .htm file for outlook signatures that includes the image inside the .htm file?
External image file that will be added as an attachment is the only way - Word (which renders HTML messages in Outlook) does not support base64 embedded images.
Try to create a new signature with an image in Outlook and see how they reference the images.

HTML email template images are not displaying in Outlook and Webmail

Thanks Everybody in advance, I have created an email template with banner image and with some widget image.
Actually instead of giving the path of the image which is stored in the server I used a code which is the decode of base64.
I used https://www.base64-image.de/ this online converter will convert the image to base64 decode for my image.
Actually my plan is instead of loading the image from the server I was using the base64 decode image so that it will be displayed in all emails like Outlook and web mail.
By referring the google I got this idea but in outlook and web mail it's not working.
After converting the image using https://www.base64-image.de/ I got the image code like this

The email client is probably blocking this type of image, or in fact any image by default. I imagine they believe that base64 encoded images present too much of risk in terms of malicious attack.
When designing emails you should expect that images will never be seen, so make good use of alt text and never have important information (e.g. text) in images on emails.
A lot of html emails include a "email looks wrong? view online HERE" link to get around this issue.
If you are worried about server costs for image hosting I would suggest using a service that will send and host resources for you e.g Mailchimp and Campaign Monitor.
These are good resources on the subject:

html restrictions in ics file

I'm developing a function (C#, ASP.NET 4) which creates and downloads a .ics file.
I'm trying to figure out what restrictions there are on the html within the X-ALT-DESC property. For example, if I send this:
X-ALT-DESC;FMTTYPE=text/html:<html><body><ul><li style="font-weight:bold">#1</li><li>#2</li></ul><table border=1><tr><td>table test</td></tr></table><span style="font-weight:bold">Site Visit Agenda</span><br/><span>8:00 AM</span><br/><span>Check in with management<br/>Facility Inspection<br/>Training and Meeting Setup</span></tr></table></body><html>
When I open the downloaded file, it opens in Outlook 2010, so that seems o.k. While the list stuff renders as I'd expect, the table border doesn't show, nor do either of the font-weight settings get rendered. (On the plus side, the html tags aren't rendered as text, it just doesn't format the alt desc like you'd see in a browser with the same HTML).
Of course, we're trying to figure out what HTML we can and cannot use to format the information we want to show up in the alt description.
Searching around, I can't find anything which talks about what's allowed and what isn't.
Thanks to anyone who has a pointer.

How can I embed large images in html documents?

I need to create an HTML file that will be stored on disk; later a user will attach this file to an email and send it to a user who will click on the file to have it display in their browser. My customer requires that the image file be embedded directly in the saved html file, not as a link to a URL that gets loaded when the doc is opened in the browser.
I've seen (and tried) the base64 code that looks like this:
<IMG SRC="data:image/gif;base64,
but my images are 150K or larger and at least in IE8, they are too big to display properly.
Is there another way to get large images embedded (not linked) into an HTML document? Remember, I won't have a program running that is interacting with the browser.
IE 8 has a data uri limit of 32k (http://en.wikipedia.org/wiki/Data_URI_scheme), which is why things are failing for you there. Also, Versions of I.E. below 8 won't support this.
That I know of, there is no way around this. You could, however, break up the image and encode separate parts of it. Since it sounds like this content isn't dynamic in any way, that might not be too hard. Otherwise, you might just want to use a CSS hack to server a different style to IE8 and below or attempt to load the image from a server for those browsers.
Thanks to all, but Albert's post gave me the answer, a bit indirectly, though. I originally created my html document as an email and imbedded the image directly in the email, mixing htm & mime. All I needed to do was change the extension on my document from .htm to .mht.
The pertinent part of my document code is:
<img border=3 width="360" height="360" src="cid:001#mime.mail"></table></div></body></html>
