Custid

After testing a number of options, this is probably one of the best image uploadery apps, great customisability, easy to use, great functions. Had a hiccup with installation because of my theme but installed fine on other themes, and support was quick and fixed it up easily!

Used another product otions app before - swapped to this one for pricing and ease of use. A little bit long to set up at first but problems were solved really fast from their support team. Overall great experience, do recommend, looks good on product pages.
