I'm using the following URL to search eBay:
http://open.api.ebay.com/shopping?callname=FindPopularItems&version=849&siteid=3&appid=app_id_removed8&MaxEntries=100&ItemSort=EndTime&ItemType=FixedPriceItem&IncludeSelector=SearchDetails&responseencoding=XML&QueryKeywords=breaking+bad&HideDuplicateItems=true&outputSelector=PictureURLLarge&descriptionSearch=false
It works, but the gallery images it returns are so small.
e.g.
http://thumbs1.ebaystatic.com/pict/2311096735168080_1.jpg
How can i make it return large images?
I've read this: eBay API - How to get large item pictures?
Which suggested I add &outputSelector=PictureURLLarge&descriptionSearch=false
but I just get the same response.
FPI is an old API call and doesn't support a lot of the parameters that newer API calls allow, such as an output selector, item sorting, description search, etc.
To get larger images, you may need to use a simple brute force find/replace on the thumbnail URLs.
If you search/replace "8080_" with "4040_" or "9696_" you'll get larger images. Try it right now in your browser with any eBay item# and it should work.
See "eBay API Gallery Image Resizing" on my eBay tech tips site for more info on this.
