That's called your signature. You need to open a photobucket account www.photobucket.com . Upload your piccies to there, then so to user options, then edit profile and copy and paste the address that looks like this
I am having the same problem, I cam actually now get them into the sig box but they are huge!!!! Need to resize and also want them in a row like nomini, mine kept appearing in a vertical line!!!
Once you have the account set up and u have uploaded your pics onto it you will have to resize then or they will be huge! Click on edit and resize them (think its the 1st size option). Then under each pic you will see 3 boxes. Copy and paste the address in the 3rd one to your sigi box.
Hope that makes sense??
You already have mastered the avatar bit! I cant get mine to work! How did you do yours???
the avitar thing was fairly easy. In the avitar box, I selected upload avitar, then clicked on choose file, (I use a mac and find it easier to have the image I am about to use on my desktop so I can find it quickly) Select the file you want and it will appear in text form, but will then appear as a picture!!!
I think that is about perfect size wise or you get told off! Shouldn't be any wider than the banner at the top with the showjumper on, and about that height.
