Compress yourself so that there is a price / quality ratio. Or use the GoogleDrive cloud.

Answer 2

Encode image to base64

Answer 3

Try, really, reduce the weight of images using online tools:
Compressor - universal, allows you to compress PNG, JPG and JPEG up to 10Mb in size
More universal resources that allow you to compress PNG, JPG, JPEG:
Puny png - Allows you to compress PNG , JPEG and GIF
Web Resizer - has relatively flexible settings
Dynamic Drive
JPEG Reducer
Picresize
Smushit
Sitereportcard
Resources that compress only PNG :
Tiny png is also not a bad resource, reduces weight quite a lot without quality loss, but PNG should be up to 5Mb
