SRB2 supports PNG patches. You usually don't need to convert them.
If you really need to make it a Doom graphic (i.e. a "lmp file" as you call it):

• rightclick the lump to convert
• go to Graphic > Convert to...
• on the drop down menu at the top, choose Doom Gfx
• ensure the "Converted Graphic" display shows the image correctly. if you're using colors outside the SRB2 palette, SLADE will pick the closest colors that exist in the palette
• change settings as you wish
• finally, click Convert (or Convert All if you're converting a lot of them)
