srckuvajpg
Srckuvajpg is a term that appears in online tutorials and sample code as a generic placeholder representing a source image in an image-processing workflow. It is not an official file format, standard, or widely recognized identifier. The string appears to combine common shorthand for a source image (src) with a word-segment that may evoke the concept of an image (kuva) and a familiar file extension (jpg). The exact origin of the term is unclear, and it does not appear in formal specifications for JPEG or widely used image-processing libraries.
In practice, srckuvajpg is used to illustrate how input images are loaded, transformed, and saved in pipelines.
Although it has no official status, srckuvajpg is useful in teaching and documentation to keep examples readable
