Some problems with adding photos

[Jan]

- Missing argument 1 for JObject::setError() - Maybe there is a confusing behaviour in Joomla! with Buttons. It is still in beta, I hope, in stable version, everything will be OK... Now, I don't get this error, but there are many users, they have problem with buttons... But there can be other problem. Phoca Gallery cannot save the file (???, not enough memory, GD library problem, rights on the server disc problem...)

- Original files are used, if something happens with thumbnail, new thumbnail are automatically created from these original files. Original files are needed, if you display the download button. Because if user click on download button, original file will be displayed, see e.g.: https://www.phoca.cz/wallpapers/

- You can change the thumbnail size: see: Advanced settings in https://www.phoca.cz/phocagallery/
