File name with an underscore looks like it gets split in IfFileExists,

[David Carlisle]

to test if pmg_ratios.svg exists you need  the argument pmg_ratios.svg
not pmg\_ratios.svg but you are also typesetting the filename (assuming the
non standard command \bf is defined) the _ will generate an error as it is
a math subscript.

You can use   \textbf{\detokenize{ pmg_ratios.svg}} \IfFileExists{
pmg_ratios.sv}{yes}{no} to make the tokens safe for typesetting in text
mode.
