Hi Kati,
1) please make sure your swf, xml, html (if used) are all located together with the pierview_files folder, but not inside it.
2) I would try doing a resync under the settings tab and see if this clears your image problem. When you made your Photo Gallery did you upload it through that program or through Visual Site Designer? Thanks
Ok helps to read lol
adding Photo Gallery to VSd there are 2 ways of doing this one way you can preview your gallery the other way you can't unless you use the add files wizard, The great CC developers made it easy as hec for us to do this. Using the flash tool( one with the lightning bolt) select the xml file that the Gallery makes, VSD does the rest adds all the files needed to make the gallery work. then you just save, select resync and it uploads, depending on the amount of images you have will determine how long it takes to upload.
The other way is uploading through the Photo Gallery itself. Just copy the code on the right hand side and paste into the page you wish in VSD using the html tool. then just upload all the files from the Gallery program , then again save in VSD and choose upload. I hope this helps some.
