RSS method does not work any more, as noted by the user review above, and the owner's reply to visit the forum is useless, since the forum itself is not searchable for guests and even using the google search on that domain (using site:domain) didn't help that much. If the owner cared enough to make a reply to a user's review, he could have already posted a link to the correct forum post, so that we don't have to loose entire day searching a simple forum.
Also, not being able to find a proper city code means that the module itself is practically useless, unless you want to use default cities.
Also, for some reason, when I finally found a way to get the city codes properly (view source in my browser and analyzing html code from yahoo weather), I realized that Serbian cities' names are not displayed at all with this module. I've checked these codes so far, which don't give any city name at all: 'SRXX0005','SRXX0006','SRXX0008','SRXX0009'
If you check Yahoo Weather page here: http://www.weather.com/weather/right-now/SRXX0005 (and also try with all the other codes I mentioned above) you'll see these are the correct codes.
All-in-all, the module seems like it is working and is fast-loading, but doesn't load the data :) So I don't really know what else to say.
On your forums, I've read nothing but blaming other people, like developers of all those SEF components, for not updating their extension list with one for RSGallery.. This could really be a big problem for this component.
Also, the developers of this component are also responsible for keeping their content elements files (for JoomFish), the same reason as above..
Oh yes, I almost forgotten another very important thing. While I was trying to somehow develop the SEF extension for myself (since no extensions found on the internet were good enough for me) I've realized you are using $catid and $limitstart variables (altogether with page=inline) to display a singe image. Is this really necessairy? For example, you could use only $id (like for download link) and from that $id you can do a single SELECT statement and retrieve those $limitstart and $catid from the #__rsgallery2_files table..
And what is gained using id in URL instead of catid, limitstart, and page? Well, if you think about it a bit, you'll see that your links for displaying a certain image, remain the same no matter if user changes ordering of image in a gallery, or if the user moves the image in another gallery. That way you will be able to get the sef extensions written by other people in your email inbox, to save your time, but this way, there is no way to create good SEF links if your links to a certain image change a lot, depending on the user actions on that image..
