I've been using IMAGEBAM a few months & it works great for loading full sized pics exactly how you loaded them. It is free & easy & seems no limit on amount of pics.
It makes a new folder everytime you load pics so easy to keep sets orginized.
It has a simple copy code for adding clickable thumbs online, but doesn't seem to allow posting the full size pic on a forum, only the clickable thumbs you see below...
It auto resizes pics to 900 wide but no change in quality & the 900 wide pic enlarges to full size with a click.
Be sure to click "family safe" when you load or it may decide your pics are adult in nature & then anyone looking at your album/photos will have adult advertisings.
Click Family Safe & no ads of any sort.
Here are a couple pics I took in HK, you can find the homepage link top left if you open the photos.
