I am currently evaluating the plugin, by testing the free version.
I have added a URL into the link textbox of an image, however when i click on the image (in preview or live website) the URL seems to have additional characters and does not resolve correctly.
Can you show us few screenshots with this issue? First one – what exactly did you put to Link tab for image, and the second one – what it’s showing when you hover mouse on image on frontend. What the difference betweend links.
Also it would be great, if you can provide us a link to a page with gallery on your website, where we can see and test this issue.
