I have had this issue since initial setup in July 2023 of WeeWX 4.10.2 using Seasons 4.10.2 skin when I switched from WeatherDisplay to WeeWX.
*barometer.png
The following images:
*barometer.png
*tempdew.png
*wind.png
*winddir.png
*wind.png
*winddir.png
*rain.png
*radiation.png
all get created as 310 x 200 instead of 500 x 180.
Where * = day, month, week, and year.
These files get scaled to 500 x 322.6 when rendered on my webpage:
(This also happens with *humidity.png, *tempchill.png, *uv.png which are not displayed.)
I have not altered any image size from the base install. I did add the [WeewxSaratoga] extension. but I don't see any interplay there.
I have not been able to find a smoking gun. Any thoughts of where I should look?
Thanks.

Without seeing your weewx.conf, and assuming you have not modified skin.conf, I would assume that the image size is getting overridden somehow in weewx.conf. Inspect the [StandardReport] stanza carefully.
If you have modified Seasons/skin.conf, then the same issue could apply there.

Thansk for the prompt reply. Yes, I did not think I was being very helpful without posting those, sorry. I am getting an error message when I try to attach a file.... (goggle groups is pretty new to me but I assume it is lack of posts).

You are simultaneously running two other reports, WEEWXtagsReport and ClientrawReport, without giving them a separate destination. Most likely, one or the other of them is regenerating the image, using the smaller format, and overwriting the Seasons version.

I'm a little surprised that this has not come up before, perhaps there are only two users of weewx-saratoga :)
In any case I have changed the weewx-sarataoga installer and realtime clientraw service to save generated content to public_html/saratoga by default. This will appear in the next weewx-saratoga release.

Thanks Gary.
If I was not ALSO publishing what WeeWx was creating as a page, I don't think I would have ever noticed. I have not figured out how/where image files (except for daywindrose.png) generated by weewx-saratoga are used.
Looks like I broke something else yesterday when I fixed the graphs. WeeWX FTP and WeeWX weather data are no longer getting updated.... they both show a timestamp about the same time as when I edited the skin.conf: https://dougengland.com/wxstatus.php

The day, week, month and year plots are used on the Saratoga 'Station Graphs' page which normally sits under 'Almanac' in an out of-the-box Saratoga install. I see on your site you don't have 'Almanac' on the navigation menu and have a different set of plots. No matter, generating the weewx-saratoga plots won't do anything other than taking up processing time and perhaps bandwidth if uploading. If you don't want to generate them you can remove the weewx.imagegenerator.ImageGenerator entry from the [Generators] generator_list setting in the WEEWXtags skin.conf. To prevent old versions from being uploaded just delete the generated files from public_html/saratoga on your WeeWX machine.

Sorry it was a couple of days before I replied, but looking at your site and status page just now I'm guessing you got it fixed.
