TIFF files not displaying in gallery - mediawiki

I uploaded some TIFF files to my wiki and tried to display them with gallery:
<gallery>
file1.tif
file2.tif
</gallery>
But, the thumbnails don't display. All I see is this:
I tried installing the PagedTiffHandler extension but it made no difference. I tried uploading with tiff extension instead of just tif and no difference.
Why won't gallery display the TIFF images?
UPDATE: I fumbled around and found that I could add $wgTiffThumbnailType = array( 'png', 'image/png' ); to LocalSettings.php and it would display thumbnail as png.
This works as long as the TIFF resolution is less than 12.5 MP.

JPG images not appearing but WEBP images are

I'm trying to build a website with HTML. I'm using an img tag to display an image. When the src links to a WEBP file, it works fine. However, when I replace that WEBP with a JPG, it no longer works. Have tried .jpg and .jpeg extensions, as well as no extension. I know that the path is correct because WEBPs work fine. Any idea what the problem is? The image displayed instead is a standard broken image logo. Thanks.

How do I view Tiff images in HTML5?

HTML5 supports JPEG and PNG image formats, but TIFF is not supported. How do open a TIFF image in an HTML5 page?
Tiff image format is not supported by the browser.
However, if you search the linked site, you can find the answer
https://github.com/iwscoop/iws.loader
It seems to be a site that provides image viewer in HTML5 for free.
I hope you have a good result.
TIFF image support is varying see here:
Display TIFF image in all web browser
Here is a good but out-dated website for TIFF images on webpages:

If that doesn't work try using a converter (Maybe something like this....)

Hope this Helps.

Tiff to Base64String convertion or display Issues

Having issues getting a Tiff image I'm receiving from USPS to render into a base64String and then display successfully using an html image tag.
MY guess at this point is either the image is corrupted in some way that dose not allow it to be converted into correct base64. Or, I am missing something when trying to display the image.
I can "successfully" convert the image to a base64String using the base .Net conversion library and several other online converters. No issues from what I can tell there. But when I go to display the image I'm unable to get it to render.
<img src="data:image/tiff;base64,{myBase64String}" alt="Return Label Image">
The full image source with my base64 string,

Any help or suggestions appreciated.
Your encoding is fine, if I paste it into the box at http://www.freeformatter.com/base64-encoder.html and hit "Decode and Download" it downloads the image. The fiddle works in Safari, but not other browsers. Main issue is that most browsers don't support TIFF.
https://en.wikipedia.org/wiki/Comparison_of_web_browsers#Image_format_support
You will need to change to a different image format, maybe PNG or JPG, before you can use the data URI in all browsers.

Problem in time to show images

I need to show pictures of direfentes formats such as JPG, GIF, BMP, TIF, PNG, PCX, but I'm not getting the images in tif and pcx formats appear in the html image tag, anyone know how I could do this?
The img tag can only handle jpg, gif, bmp and png files. To display i.e. a tiff file you can use the embed tag.
<embed width=xxx height=xxx src="tiffdocument.tif" type="image/tiff">
More variations here
Most browsers can't display TIFF and afaik no browser can display PCX images, using standard <img> tags.
A solution would be to convert the image to a supported format, either manually or automatically (using php or server-side language).
Repeat of: Display TIFF image in all web browser. It's browser support issue.

opening a tiff image in IE

Is it possible to open Tiff images in IE, just like BMP opens in IE.
When i try to assign an iframe source as a tiff image it pops up a save dialog. i want to display tiff image inside an IE page.
Following is a sample which i was trying
<iframe src='C:\Users\XYZ\Desktop\Untitled.tif'; id ='hello'></iframe>
IE does not natively support TIFF images. You have three options:
Use a browser plugin such as: http://www.alternatiff.com/
Convert the image on the fly before presenting to the browser.
Batch convert the images to another format.
The preferred solution will depend on your situation.
Internet Explorer doesn't support TIFF images natively. You need a plugin for this to work. Check http://www.alternatiff.com/
Try the classic "applet" instead...
