Pin-sharp here and I've just checked it in another browser to confirm I'm not seeing a locally cached copy.
Even though this forum tells your browser to resize large images to fit the column width, the resistor values and 'multimeter' are readable as is with a 1024px screenwidth. The jpeg itsself opened in a new window is 1278x719px and is fully readable, right down to the clock on the O.P.'s windows taskbar.
However for anyone contemplating posting something similar (i.e. any line drawing or diagram), *PLEASE* crop irrelevant crud from the edges, reduce the colour depth to 256 or even 16 colours and save as GIF or PNG. That gets you the most bang from your filesize limit buck if the original is *NOT* a photo. JPEGs with medium to high compression blur fine detail so should be avoided for line art. If you don't have anything better to do it in, grab a copy of IrfanView, which also has a very handy RIOT plugin for crunching JPEGs just enough to squeek through any specific file size limits.
