IMAGE GALLERY needed for my eBay advert (urgent)

Hi people, I use dreamweaver to design my ebay advert template. All images are loaded from my webspace. I'm stuck and running out of time on the bit I need help. I want a image gallery in my adverts, I have the thumbnails (or will have) I want the larger version I have of each thumbnail to load into a frame. Here is a example on ebay - [login to view URL];item=300561095939 and [login to view URL];var=&hash=item6b1b6a5765 I would need instructions on how to edit the code so I can change from say 30 thumbnails down to 3 for different items I have. I also require a section with tabs like the advert example on ebay i have linked, where I can have different text by clicking the tabs. This is for postage/returns/terms info (for example) I would also like the following if it is at all possible..... -I have 1000+ ads to do -ads are all the same except each advert has a unique number that is in all the picture files. eg .....xxxxx-(PU)[login to view URL] xxxxx-(PU)[login to view URL] I don't need to change the text but i needn to change xxxxx I wanted a solution where i change the code once in the html header and it auto uses that number through out the html if possible. SUMMARY - gallery that shows thumbs and when clicked loads main image in a specific place - has to work in ebay - may need a few variations to suit my different items (or instructions) - a tabbed text box that changes text depending on tab selected - a way to change all the image numbers (but not text) by inserting that number just once somewhere. WHAT I WILL SUPPLY My HTML FILE with a JPEG OF THE GALLERY in the place where I want the gallery. The jpeg will illustrate how it should look. MSN MESSENGER would be handy to communicate during the process. I am in the UK and work MON-SAT 8-5.30 I look forward to working with you on this. Regards John
