I heard you had to pay to upload more than one pic or to add a subtitle is this true?
At one time it did cost .15 cents for pictures beyond the one free one they gave, but I think that often goes by the wayside as they frequently offer free pictures.
If you do get going on any regular basis, learn basic html and you can include as many FREE pictures as you want in the middle of the text you write about your item (see examples in this post).
I usually post about 10 pictures of an item and these are LARGE and detailed with macro closeups of labels, quality of material, namebrands, etc. I have gone up to 20 or so pics on some items. At a time when they DID charge for extra pics it was a good savings, but beyond that, the quality and size of the pics is a big attraction IMO.
I feel interspersing text like this with photos helps draw buyers down the page IF they are actually looking for a given item.
See how the images and text approach works. Anyway, it works for me. Each person has their own approach
and feelings about such things. Do what works for you and keep it simple in the beginning.
Here's another example.
The water testing meter above brought $400 on eBay. My cost was $30 from a flea market seller who didn't know what he had.
