I have tried a lot of online OCR services, but no one of them produced correct list of nicknames on the screen.
Are there any ways how to get correct nicknames from the screen?

I've seen on many websites where they have an image, then over that image they float some + symbol icons in various places. You can then click on these + symbol icons and they expand to display some text. I'm not sure what you would call this, so I don't even know what to Google to try and find something about how to do this. My Googling so far has turned up nothing. I'm using Wordpress and am wondering if anyone knows of a Wordpress plugin or a way to accomplish this, or at the very least what terms I could Google to try and find examples of how to create something like this.
I would like to digitize a book in a similar way to the reCaptcha project. Is there already a system for inputing an image and then outputting little images cropped around words? Any ideas on how to do this?
You should look into the Tesseract OCR project on which reCaptcha was probably based. It has the capability to output the coordinates of recognized words. Then you crop the page to those coords and you are done.
If you just want to split the image in multiple images one word each you could try to find the word bounding boxes and then take those co-ordinates for the splitting. This can be done by taking histograms/projections of the document in horizontal direction and then for each line in vertical direction. An example algorithm with some pictures describing the idea can be found in this paper: "Document Page Decomposition by the Bounding-Box Projection Technique" (http://haralick.org/conferences/71281119.pdf). You could implement this in OpenCV.
Alternativly, you can use Tessaract as mentioned by beppe9000. Perhaps this helps: Getting the bounding box of the recognized words using python-tesseract
But then you get the whole complexity of training OCR even though you only want the bounding boxes.
Working on a project for Retrieving content from a given image and compare with other images in the repository and list out the matching images.
what should be right approach to do it so that the search wont slowdown eventually.
What I was planning to do as a first level of filtering was to use any Image Querying (CBIR technique) to retrieve images matching the pattern of given image.
Then do OCR to get the image content and do a match check.
Please let me know if there is any better approach for this.
Steps done
Softwares
1. Tesseract OCR
2. Image Magick - For image cleaning
3. Textcleaner script
Found out the image orientation using Image Magick software
Convert package has a feature to find the image orientation using the EXIF data which is not that useful.
For this image was rotated 90 degree thrice and the ocr data for each was compared with the other to find the correct orientation. ( image with maximum number of words wins)
OCRed the image to get the text and applied filtering to get the bill no, date and amount.
on success stores the details on DB for future search
on failure
Created 10 different images with different filters (gray scale mode and sharpment applied)
OCRed all images and found out the required data form all the data got.
Saved data is used for future search feature to eradicate duplication
I have been working hard on assembling photos into a travel blog. Currently I am reading about how to make full page image carousels. The specific problem I have is this: I want to have an image carousel of 100 pictures. At different points in the blog I want the user to be able to enter the same carousel at different images in the sequence. Currently I have to duplicate the code for the 100 images at each point in the blog. I am trying to figure out how to refer to the same html from different parts of the web page. Here is an example:
https://bwanaaa.github.io/flicktest/
The first image is a full bleed cover. The next two galleries are the same gallery but different starting points. I had to list all 10 images in the html TWICE to achieve this. You can imagine how verbose the html gets if i have 50 images with 10 entry points.
Here is a codepen to experiment with:

Is there a way to have a 'subroutine' in html?
This can't be resolved through HTML alone. You'll have to implement further JS functionality, or find a different plugin.
Here is a plugin that is closer to what you're looking for:
https://github.com/stylehatch/photoset-grid
Demo:
http://stylehatch.github.io/photoset-grid/
it makes a grid of photos, then you also add the lightbox functionality, whatever photo they click on, it will go to that photo in the photoset, and also have navigation icons comparable to a carousel.
I managed to add embedded assets to htmlText of my TextArea like described here (Sly_cardinal's post, currently the third one):
Unable to access embedded images in htmlText
But all the images appear in the top left corner (overlayed)!
Interesting is that the place where the images should be, is actually empty and the text wraps around it, like they were there. But they are all in the corner.
I'm using large p tags for the text and all html displays perfectly where it should be. My only problem are these images.
Hope somebody has at least an idea. Thanks.
P.D. sorry for not showing code, it's cluttered at the moment with other things. But I hope the description is enough to get some useful tips.
P.D. 2. I did a test now with exactly the same code but using normal path to png file instead of asset and that works!.
