I'm not sure about size budget, but adding support for jpeg/gif image 
formats will make lif easier for qbzr *users*, not developers.

Actually there is 2 forms of each image support plugin, e.g.

qjpe4.dll and qjpegd4.dll

The former is 160KiB in size and the latter is 1.3MiB in size.
I assume "d" variant has debug info inside. So deleting all "d" dlls
still give me images support but in this case size of imageplugins 
shrinks down to 918KiB. In the installer it would be around 500KiB or so.
