I just would like to know if the "Recently Uploaded Images" can be just put two photos uploaded in one section.

for example, all images that are uploaded in the P!NK Discussion area will be the only photos that are in this section at the bottom of the forum, not the whole forum? i think this makes sense.

The display of images is subject to certain conditions:

Only images over 200px wide are displayed;
Images appear to members based on topic and image visibility permissions. So if the member doesn't have permission to read the topic where the image was posted, they won't see that image in the block. Similarly, if forum guests do not have permissions to view images in a particular section, these images will not be present for them via this new feature;
The images contained in certain BBCodes (quotation, hide, etc.) are excluded from display;
Images hosted on certain external services that have now been discontinued or paid for (TinyPic for example) are excluded from display;
After adding a new image, it can take up to 5 minutes for it to be displayed in the block.

As well, my colour usernames aren't working? Admins are mean't to have "Pink" usernames but for some reason its not showing up on the forum but in the admin background it is.
