For our forum we use the platform IP Board. You can click images attached to posts to open a larger version in a lightbox. We recently noticed that the lightbox is not responsive so, even on desktop, it gets cut by the window frame. We need a developer to make the lightbox size automatically adapt to the windows size (both on mobile and on desktop). If you know how to customize the IPBoard theme, it will be a really quick job. The developer needs to know which files to modify without breaking the layout. Please start your application with the word FCF. Please provide your budget.
