Here are the few issues I noticed:
1. The module does not display the image from the specific image tab in K2. It only displays images, which are inside the content. This is one of the best features in K2, especially in terms of automatic image handling. IMO everyone would expect this to work in that way or in both.
The bug 1 also applies with JA News Pro.
2. The symbol limit in JA News FP applies only if the item has a picture in the content itself. Otherwise the full intro text is displayed.
3. mod_k2_content doesn’t work on pages where JA News FP is loaded.
4. Images and HTML is not stripped in JA News FP when using K2. So basically two or even 10 images could be displayed there instead of the text.
I really hope, you will finish well the work on JA News FP and JA News Pro with K2, as this will be the major reason for many to use Teline 4!!!
