-Photoshop Image Resources consists of a sequence of blocks, each with a numeric ''Resource ID'' indicating the type of data stored in the block. Each block also contains a name, but the name is often left empty.
+The format is presumably derived from [[Macintosh resource file]] format. Except in an actual Macintosh resource file, it is serialized as a contiguous sequence of blocks.
 Each block usually begins with the ASCII characters "8BIM", a signature that appears in several Photoshop formats. Other block signatures that have been observed are "MeSa" (apparently associated with ImageReady), "PHUT" (apparently associated with [[PhotoDeluxe]]), "AgHg", and "DCSR".
