#1413 When exporting, images with the same character ID are overwritten
When exporting images with the same character ID (so they will have the same name after export), the default behavior seems to be to overwrite the file. Is it possible to add auto-rename or option to rename conflicting files while exporting? Have to export each image with the same name one at a time, right now.
Images from same SWF should have different character ID. I don't see a point in exporting images with the same character id to different files. If you export multiple SWFs, then select another directory. Or if you select multiple SWFs in FFDec, directory per SWF should be automatically created.
