Email servers usually have a gross limit of 10 MB to Ovid them being overwhelmed.

10 MB gross translate into about 6 MB net (with a bit of slavery margin), because the email protocol is based on ASCII.

EVERY email in it's entirety including attachments must be encoded in ASCII.

Transferring larger amounts of data by email thus is not a good idea because you consume about twice the size of transfer than the size of your payload.

If you don't have access to upload space to place the files for downloading then use a free data transfer service like WETRANSFER.COM.

Up to 2 GB per transfer.

AND you get a confirmation by email when the recipient did transfer the file/files OR did not download them within a week.

File size, yes, but says nothing about image size, the X-by-Y pixel resolution.
Which gets to the part about using GIMP, setting the image size, cropping and
setting the quality percentage.

THOSE are what, ultimately, determine file size.

The point being that a few minutes with GIMP could reduce that 2.5MB file to a
0.4MB file without loss of the relevant visual information that needs to be
conveyed to the insurance company.
