Hey and thank you for so quick reply!
I tested out the choice 1 and it would have been great choice unless i didn't plan to post out also icons.. sigh i'm picky, BUT.. someone else can find the info here now and use it.
I finally solved it out my ways, as using the resizing feature you mentioned about(which made images smaller permanently), and adding to description a pop up java script without locations etc...including the full sized image/and to header the function code.
I decided also to not to go with the usersubmitted part, actually i hassled the code so badly i ended up taking whole membership part away , also lightbox and zip downloads..
I noticed too my GD 1.62 probably doesn't support gifs and i had to put gif files to separated pop up too..it couldn't create the thumbnails at all, and I read from this forum GD 2 doesn't support them so i suppose GD1.6 doesn't either. Anyhow, i like how it is now,and as i'm redoing my whole site next month the layout can wait still..i can slowly upload everything there to wait now.
And.. what i really like the most is the fact it's perfectly coded.. no errors nothing.. After trying out at least 5 different image galleries this is a pearl and i'll get my hands to it later on again if i need to put back the login forms and random images. It will work greatly for my images, not for my downloads but but..maybe in future
Thanks so tons for your help.. and very merry Christmas as well:=)
