I updated a captivate module, which I published as html for web only, and ensured that I'd replaced the play icon in c-drive with a transparent icon, because I didn't want it showing over an image (into which I had inserted a 'fake' but pretty play button). I also replaced the open and collapse toc icons in the TOC settings. When I previewed on my computer it all looked fine, but when I sent the files to a colleague who then uploaded it to our website, the original default play icon and TOC open and collapse icons appear again! Why would this happen as these no longer existed in my cdrive when I published the module. Is it to do with having someone else upload the files to the website?
That is very strange, because I follow that workflow (which I explained in a blog) for all my projects. Even the TOC buttons, which I mostly also replace by an empty png, because I create a real Toggle button. You did publish the file yourself? I have no idea how uploading could be the cause, but if the person did republish it would explain the appearance of the Play icon. Not really the other icons, unless another theme was used.
