Analysis Advice

Sample is a picture (JPEG, PNG, GIF etc), nothing to analyze
Sample has a GUI, but Joe Sandbox has not found any clickable buttons, likely more UI automation may extend behavior
Sample tries to load a library which is not present or installed on the analysis machine, adding the library might reveal more behavior
