This image shows some kind of formula that could be converted to TeX . Storing formulas as images makes it harder to change them. TeX also helps making sure that they all use the same font and size. A replacement has been proposed:
X
f
↗
↓
π
i
Y
→
f
i
X
i
{\displaystyle {\begin{array}{r}X\;\;\\{}^{f}\!\!\!\nearrow \quad \downarrow ^{\pi _{i}}\\Y{\xrightarrow[{\ f_{i}\ }]{}}X_{i}\;\end{array}}}
In your article, replace the image with:
<math>\begin{array}{r}
X \;\; \\
{}^f\!\!\!\nearrow \quad \downarrow^{\pi_i} \\
Y \xrightarrow[\ f_i \ ]{} X_i \;
\end{array}</math>
