To rename an asset, first select it in the grid. Then open the Asset Information panel (keyboard shortcut T) and click on the Pencil button at the bottom of the panel to rename the file.
The dialog that comes up lets you choose a new name for the asset. Type in the new name and click on Rename to process the asset.
Note that the asset's original extension will always be preserved.
Tip: By selecting several assets and using the renaming function as outlined above, you can enter a prefix which will be common for all the files that are being renamed. FotoWeb will automatically add running numbers to the renamed files to give them unique names.
Preservation of album links when assets are renamed
If an asset has been added to an album, it's the asset's file name that links it to the album. When renaming files in FotoWeb that have been added to an album, FotoWeb also updates the album's link to the file with the new filename.
However, if an external system is used to rename an asset that exist in a FotoWeb album, the asset will disappear from the album.
