A lot of information

Tank’s Connor,
You have given me a lot of information.
For my question I found a Javascript function that read images but I can’t use it when I upload with item “File Browse” (Blob don’t exist before submit)
I waiting for the DBAs to upgrade ApEx to use MLE.

You're right to explore options for extracting image dimensions from a BLOB in ApEx, and Connor's points about Oracle 19c dropping multimedia support make this a bit trickier. That Stack Overflow thread provides a method for reading binary files directly, but as you said, it's not the most reliable approach.
Since you're using ApEx, an alternative could be leveraging external tools like ImageMagick via an external table or a PL/SQL web service to process the images before inserting them into the database. Another option is using Java stored procedures to extract metadata.
