Third post, first picture

By using option - save picture - i download "downloadfile.bin".
By using option - open picture - and later save picture i download "resized-1xx......." without any file format

Sorry, I know there are also polish users, so it was easier to write this way.
In "old" opera i was switching between tabs using "right mouse button + scroll". Is it possible in opera 28?

Używając "starej"opery mogłem przełączać karty trzymając ppm i scroolując. Czy w opera 28 jest to możliwe?
